The purpose of this study is to determine whether the administration of propranolol is effective in the treatment of the retinopathy of the prematurity.
Retinopathy of Prematurity (ROP) is still a major cause of blindness in children in developed countries around the world, and an increasing cause of blindness in developing countries. The ablation of the retina with photocoagulation by laser or cryotherapy reduces the incidence of blindness by suppressing the neovascular phase of ROP. However, the visual outcomes after treatment are often poor. The development of ROP depends largely from vascular endothelial growth factor (VEGF). The reduction of VEGF expression in the neovascular phase might prevent destructive neovascularization in ROP.
The purpose of this study is to evaluate whether the administration of propranolol is safe and is able to reduce the incidence of blindness by suppressing the neovascular phase of ROP compared to a control group receiving conventional laser therapy.

To determine the effect of propranolol on retinal neovascularization due to proliferative diabetic retinopathy (PDR).
Retinopathy of prematurity (ROP) is a major complication of preterm birth and has been associated with later visual and nonvisual impairments.
A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterized by vascular dilatation, proliferation, and tortuosity, edema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (Dorland, 27th ed)
A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
